What if 'Back to the Future IV' Happened?

Since 1990, we've all been holding on to our seats waiting for an announcement that BTTF IV would be a real thing. Unfortunately, Robert Zemeckis has said a million times before that Back to the Future was finished for good. But, what if BTTF IV was made to be released on October 21st, 2015? Here's a little fan cast for hopes maybe it one day it will happen.

Dylan O' Brien as Marty McFly

MCFLY!

Dylan O' Brien has a lot of great potential in the film industry. He's well known for the television show "Teen Wolf" and he's currently working on The Maze Runner films. O' Briend can definitely pull off Marty McFly's akwardness, as proven in his role on Teen Wolf. Plus, O' Briend has played drums in a bad named "Slow Kids At Play," giving him acting and musician cred. Plus 1 for Dylan!.

Bill Hader as Dr. Emett Brown

GREAT SCOTT!!

While this casting may seem controversial, I believe Hader is perfect for the role of our favorite scientist. As seen in Saturday Night Live, Hader can go from A-Z as Christopher Lloyd did with Doc Brown. His characters were wacky and hilarious. And with a little bit of make up, he'd look the perfect age to play Doc Brown.

Lea Thompson as Lorraine McFly

Calvin Kline... is that your name?

Lea Thompson definitely looks old enough to play Marty's mother. She did great in the role and I'm sure she'd be honored to come back. And what perfect way to make a reference to the original movies?

Crispin Glover as George McFly

This guy must be scared of Darth Vader now...

Crispin Glover was absolutely perfect as George McFly. While, he looks a little young for his age... some make up could do the trick. And Glover's character was just the cliche' adorable nerd. Need I say more?

Emma Watson as Jennifer Parker

I'm Old!

Emma Watson is a great actress with much potential in the industry. Though she hasn't been in any blockbuster films since Harry Potter. Though recently, she was casted as Belle in a live action version of Beauty and the Beast. She has the looks and the talents to play Marty's girlfriend.

Thomas F. Wilson as Biff Tannen

HEY MCFLY, YOU BIG BUTTHEAD!!

Thomas F. Wilson definitely looks his age to play Biff Tannen. His character was the definitive high school bully we all hated... which made us love and hate him more.

Now, the basic idea of the film is that Doc comes back from the future to tell Marty they've created an alternate 2015... which turns out to be our own. So, they have to travel back to sometime in the past to change something that they've messed up big time.
